  This useful work identifies a key role for Tachykinin-1 parasubthalamic neurons in avoidance learning. At present, the evidence for the conclusions regarding fiber photometry, viral transfection, reporting of behavioral outcomes, and pathway-specificity is incomplete. This work will be of interest to neuroscientists studying neural mechanisms for avoidance and aversion.

  This study examined the role of the dorsal medial prefrontal cortex of mice in anticipating reward-value switch points in a two-armed bandit task. They demonstrate the dorsal medial prefrontal cortex is involved in task performance and use model-based methods to uncover the algorithmic processes affected by prefrontal cortex perturbations. If the claims were supported, this would be a valuable finding. Unfortunately, the reviewers recognised significant issues with the task design and analyses, making the evidence to support the role of the prefrontal cortex in anticipation of switches inadequate.

  This manuscript describes work that is fundamental to our understanding of the mechanism of how stress regulates the noradrenergic system and the CRH system. Using a combination of ex vivo physiology and in vitro methods, the study provides compelling evidence as to the signaling mechanisms of how glucocorticoids impact adrenergic GPCRs in CRH cells via receptor trafficking. While the ex vivo work is specific to the hypothalamus, the mechanisms here could be extrapolated and investigated in other brain regions that may have similar signaling regulation.
